Answer:
Yes this claim is correct.
Explanation:
The shear stress at any point is proportional to the velocity gradient at any that point. Since the fluid that is in contact with the pipe wall shall have zero velocity due to no flow boundary condition and if we move small distance away from the wall the velocity will have a non zero value thus a maximum gradient will exist at the surface of the pipe hence correspondingly the shear stresses will also be maximum.
Answer:
False
Explanation:
COP is Coeficient of performance, it relates useful heat moved with work consumed, it is used in refrigerators and heat pumps.
For refrigerators the useful heat is the one extracted from the cold reservoir. Therefore:

This often exceeds 1.
